T1 - Soliton radiation beat analysis of optical pulses generated from two continuous-wave lasers JF - Chaos : an interdisciplinary journal of nonlinear science N2 - We propose a fibre-based approach for generation of optical frequency combs (OFCs) with the aim of calibration of astronomical spectrographs in the low and medium-resolution range. This approach includes two steps: in the first step, an appropriate state of optical pulses is generated and subsequently moulded in the second step delivering the desired OFC. More precisely, the first step is realised by injection of two continuous-wave (CW) lasers into a conventional single-mode fibre, whereas the second step generates a broad OFC by using the optical solitons generated in step one as initial condition. We investigate the conversion of a bichromatic input wave produced by two initial CW lasers into a train of optical solitons, which happens in the fibre used as step one. Especially, we are interested in the soliton content of the pulses created in this fibre. For that, we study different initial conditions (a single cosine-hump, an Akhmediev breather, and a deeply modulated bichromatic wave) by means of soliton radiation beat analysis and compare the results to draw conclusion about the soliton content of the state generated in the first step. In case of a deeply modulated bichromatic wave, we observed the formation of a collective soliton crystal for low input powers and the appearance of separated solitons for high input powers. An intermediate state showing the features of both, the soliton crystal and the separated solitons, turned out to be most suitable for the generation of OFC for the purpose of calibration of astronomical spectrographs.

In response to these needs key competencies in understanding, developing and using new digital technologies are being brought into focus in school and university programmes. The IFIP TC3 conference "KEYCIT – Key Competences in Informatics and ICT (KEYCIT 2014)" was held at the University of Potsdam in Germany from July 1st to 4th, 2014 and addressed the combination of key competencies, Informatics and ICT in detail. The conference was organized into strands focusing on secondary education, university education and teacher education (organized by IFIP WGs 3.1 and 3.3) and provided a forum to present and to discuss research, case studies, positions, and national perspectives in this field.

Auch die akademische Debatte um die Orientierung deutscher Außenpolitik und die ihr zugrundeliegenden Interessen hält seitdem an. In welchem Verhältnis stehen Normen und Werte einerseits und pragmatische, meist wirtschaftliche Interessen andererseits zueinander? Wie verhält sich die deutsche Außenpolitik zur europäischen? Beeinflusst oder dominiert die deutsche Position gar die europäische? Am Beispiel der deutschen Außenpolitik gegenüber den zentralasiatischen Staaten Kasachstan, Kirgisistan, Tadschikistan, Turkmenistan und Usbekistan werden diese Fragen diskutiert. N2 - Since 1990 the reunited and sovereign Federal Republic of Germany tries to define its role in the world. It is linked to an academic debate on the coherence of German foreign policy and underlying interests. How do norms and values on the one hand relate to pragmatic, primarily economic interests, on the other hand? How is the German foreign policy linked to the European one? Does the German position influences or even dominates the European orientation? These questions will be discussed using the example of the German foreign policy towards the Central Asian states Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan.

T1 - Mad2 Inhibitor-1 (M2I-1): A Small Molecule Protein-Protein Interaction Inhibitor Targeting the Mitotic Spindle Assembly Checkpoint JF - ACS chemical biology N2 - The genetic integrity of each organism depends on the faithful segregation of its genome during mitosis. To meet this challenge, a cellular surveillance mechanism, termed the spindle assembly checkpoint (SAC), evolved that monitors the correct attachment of chromosomes and blocks progression through mitosis if corrections are needed. While the central role of the SAC for genome integrity is well established, its functional dissection has been hampered by the limited availability of appropriate small molecule inhibitors. Using a fluorescence polarization-based screen, we identify Mad2 inhibitor-1 (M2I-1), the first small molecule inhibitor targeting the binding of Mad2 to Cdc20, an essential protein-protein interaction (PPI) within the SAC. Based on computational and biochemical analyses, we propose that M2I-1 disturbs conformational dynamics of Mad2 critical for complex formation with Cdc20. Cellular studies revealed that M2I-1 weakens the SAC response, indicating that the compound might be active in cells. Thus, our study identifies the SAC specific complex formation between Mad2 and Cdc20 as a protein-protein interaction that can be targeted by small molecules.

Der Historiker Xenophon von Athen (427–ca. 355 v. Chr.) hat in seinen Schriften über zwei Träger dieses Namens berichtet und sie durchaus unterschiedlich bewertet: Kyros II. («der Große»), Mehrer des Reiches, sowie ein Jahrhundert später Kyros, Sohn des Dareios und jüngerer Bruder des Perserkönigs Artaxerxes II. Der ältere Kyros ist namengebender Protagonist eines Fürstenspiegels (der Kyropädie), wird also grundsätzlich positiv und als ein Vorbild für andere dargestellt. Am erfolglosen Kampf des jüngeren Kyros um die Krone des Perserreichs hatte Xenophon als Offizier griechischer Söldner selbst teilgenommen. Aus dem Vergleich von Darstellung und Bewertung der beiden Fürsten lassen sich die Ansprüche Xenophons an einen idealen Herrscher ableiten, was hier unternommen werden soll. Zugleich ermöglichen diese Ergebnisse, Xenophon als Historiker und politischen Denker in der zeitgenössischen Debatte um die beste Staatsform einzubetten. N2 - «Cyrus» as the name of a prince occurs thrice in the annals of the Persian Empire. e historian Xenophon of Athens (427–about 355 BC) wrote about two bearers of that name: Cyrus II. («the Great») and, roughly a century later, the younger Cyrus, son of Darius II. and younger brother of Artaxerxes II., the Persian king. e older Cyrus gives his name to a mirror of princes (the Cyrupaedia) and is portrayed positively and as an inspiration to others. Xenophon himself had been an officer in the failed attempt of the younger Cyrus to win the Persian throne by military force. By comparing the way Xenophon depicts and judges both princes, we can deduct what our historian expected of an ideal ruler. ese expectations place Xenophon in the wide contemporary spectrum of opinions on the best constitution (monarchy, oligarchy, democracy).

Created in the aftermath of World War II by its victors, the UNSC’s constellation looks increasingly anachronistic, however, in light of the changing global distribution of power. Adapting the institutional structure and decision-making procedures of the UNSC has proven to be one of the most difficult challenges of the last decades, while it is the institution that has probably been faced with the most vociferous calls for reform. Although there have been changes to the informal ways in which outside actors are drawn into the UNSC’s work and activities, many of the major players in the current international system seem to be deprived from equal treatment in its core patterns of decision-making. Countries such as Brazil, Germany, India and Japan, alongside emerging African nations such as Nigeria and South Africa, are among the states eager to secure permanent representation on the Council. By comparison, selected BRICS countries, China and Russia - in contrast to their role in other multilateral institutions - are permanent members of the UNSC and with this, have been “insiders” for a long time. This renders the situation of the UNSC different from global institutions, in which traditionally, Western powers have dominated the agenda.

This article argues that an important yet missing piece of this puzzle is the systematic exploration of the political use of policy knowledge. While much of the recent debate has focused on the question of how the substantive use of knowledge can improve the quality of policy choices, our understanding of the political use of knowledge and its effects in the policy process has remained deficient in key respects. A revised conceptualization of the political use of knowledge is introduced that emphasizes how conflicting knowledge can be used to contest given structures of policy authority. This allows the analysis to differentiate between knowledge creep and knowledge shifts as two distinct types of knowledge effects in the policy process. While knowledge creep is associated with incremental policy change within existing policy structures, knowledge shifts are linked to more fundamental policy change in situations when the structures of policy authority undergo some level of transformation. The article concludes by identifying characteristics of the administrative structure of policy systems or sectors that make knowledge shifts more or less likely.

The present Visual World eye-tracking study tested bilingual heritage Russian–English adults and investigated how they interpret of sentences like Every alligator lies in a bathtub in both languages. Participants performed a sentence–picture verification task while their eye movements were recorded. Pictures showed three pairs of alligators in bathtubs and two extra objects: elephants (Control condition), bathtubs (Overexhaustive condition), or alligators (Underexhaustive condition). Monolingual adults performed at ceiling in all conditions. Heritage language (HL) adults made 20% q-spreading errors, but only in the Overexhaustive condition, and when they made an error they spent more time looking at the two extra bathtubs during the Verb region. We attribute q-spreading in HL speakers to cognitive overload caused by the necessity to integrate conflicting sources of information, i.e. the spoken sentences in their weaker, heritage, language and attention-demanding visual context, that differed with respect to referential salience.
